Using multiple sensors

[goober]

Hi Jon,
Could you use two PIR sensors on a prop-1 to run two different relays?

I'd like the first sensor to start a fogger. Then when the mark gets to the prop the second sensor with turn on the a sopt light & air cannon. I'd like two sensors so I don't have to guess when to trip the prop. I don't want it to go off too soon or after it's been passed up.

I spent 4 hours with Vixen getting the prop-1 sequence and sequence generator add-ins installed. Now I'm getting a "template file is missing" error. I'm stuck so  I'm back to the old way.
If two sensors could be used how I write them in the prograam? Here is the short program I'v come up with:

I don't mean to seem harsh, but I'm having touble convincing you that to use our forum guidelines: one topic per thread, please....

Yes, you can use multiple PIRs.  I'm a few minutes from boarding a plane.  When I get home tonight I'll whip up a little demo.  Please post your Vixen questions in the Vixen section of the forums.

Hi Jon,
Do you have a sample or could show me how to use two PIR sensors on a prop-1 to run two different relays?

I'd like the first sensor to start a fogger. Then when someone gets to the prop the second sensor will turn on a sopt light & air cannon.

Here's a framework that you can tweak.

Is there a way to float the pir2 sequence in the program? I would like the pir1 to trip & run for 45sec and any time during the program the pir2 could be triggered once. With this program the pir1 will run forever until the pir2 is tripped then the pir1 45sec timer starts.
Also is there a way the program will reset after 60sec even if the pir2 hasn't been tripped, or does the program need to complete every step before it can be reset? or should I be using two prop-1s to run this prop?

Forgive me, Goober, I'm under the weather a bit today and having trouble understanding the description.  Please restate it, step-by-step, one step per line, please.  This exercise will help me, and will help you; once you see your steps translated to code the code will make more sense.

And there's no need to for two controllers -- once I fully understand what you want I will be able to code it for you.

Ok

Sequence I'd like to have programed:
   1- Pir1 trips a relay & goes for 45sec.
   2- Anytime while pir1 relay is running pir2 can be triggered. (for about 1/5sec)
   3-After the 45sec the program will reset even if the pir2 was never tripped.

Limits:
   Pir2 can only be triggered while pir1 relay is activated.
   Pir1 time line is unaffected by pir2

Problem I'm encountering:
   Pir1 time does not begin until pir2 has been tripped. in other words pir1 will run all day until pir2 has been triggered then the 45sec timer starts.

Okay, we're getting there -- but you have a bunch of things defined (e.g., fogger, lights, etc) that you're not telling me how to operate -- give me those details, too.  To simply say "PIR 1 program" is vague and will just lead to more versions of the program than needed.

I know, the devil is in the details, but once you get used to spelling out the details, programming is a pretty simple chore.

[goober]

 1- Pir1 trips a relay for a fogger & goes for 45sec.
   2- Anytime while the fogger is running pir2 can be triggered. (for about 1/5sec)
          (Pir2 trips a relay for both a spot light & air cannon)
   3-After the 45sec the program will reset even if the pir2 was never tripped.
This is what I have so far:

Main:
  timer = 0
Check_pir1:
     PAUSE 5
     timer = timer + 5 * pir1
     IF timer < 200 THEN check_pir1
    HIGH fogger                                    'fogger on
  timer = 0
check_pir2:
    PAUSE 5
    timer = timer + 5 * pir2
    IF timer < 200 THEN check_pir2
    HIGH lightcannon                          ' light flashes & cannon fires
    PAUSE 50
    LOW lightcannon
    PAUSE 45000                               ' fogger runs 45sec
    LOW fogger                                  ' fogger off
  PAUSE 10000                                 ' 10sec til system resets
    GOTO reset

Did this thread move somewhere else?  I was interested in seeing the final outcome of the code as I have a very similar need.
